Abstract
A subsurface defect detecting device for cylindrical components and method thereof are provided. The subsurface defect detecting device for cylindrical components includes: an electric rotating platform, a three-jaw chuck, a first linear supporting base, and a second linear supporting base. The three-jaw chuck is mounted on the electric rotating platform, and the three-jaw chuck is configured to fix a workpiece to be detected. The first linear supporting base and the second linear supporting base are arranged close to the electric rotating platform, and the first linear supporting base and the second linear supporting base are in contact with each other and are perpendicular to each other. The present disclosure achieves optimal laser ultrasound detection angles by incorporating a moving device, determining the appropriate laser ultrasound detection angle for cylindrical components with different curvature radii, thereby reducing the impact of uneven surfaces on the detection results.
